Partial credit, 8.3.22-T Question Help A group of students estimated the length of one minute without reference to a watch or clock, and the times (seconds) are listed below. Use a 0.05 significance level to test the claim that these times are from a population with a mean equal to 60 seconds. Does it appear that students are reasonably good at estimating one minute?

Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses?
A.
H0: μ=60 seconds
H1: μ>60 seconds
B.
H0: μ≠60 seconds
H1: μ=60 seconds
C.
H0: μ=60 seconds
H1: μ≠60 seconds
Your answer is correct. D.
H0: μ=60 seconds
H1: μ<60 seconds
Determine the test statistic.
nothing (Round to two decimal places as needed.)

the correct is answer is a 9-sided polygon!

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
